Abstract [en]
Background
Exposure to extremely low-frequency electromagnetic fields (ELF-EMF) was in 2002 classified as a possible human carcinogen, Group 2B, by the International Agency for Research on Cancer at WHO.
Methods
Life time occupations were assessed in case-control studies during 1997-2003 and 2007-2009. An ELF-EMF Job-Exposure Matrix was used for associating occupations with ELF exposure (T). Cumulative exposure (T-years), average exposure (T), and maximum exposed job (T) were calculated.
Results
Cumulative exposure gave for astrocytoma grade IV (glioblastoma multiforme) in the time window 1-14 years odds ratio (OR)=1.9, 95% confidence interval (CI)=1.4-2.6, p linear trend <0.001, and in the time window 15+ years OR=0.9, 95%CI=0.6-1.3, p linear trend=0.44 in the highest exposure categories 2.75+ and 6.59+ T years, respectively.
Conclusion
An increased risk in late stage (promotion/progression) of astrocytoma grade IV for occupational ELF-EMF exposure was found.
